Are The two parts of a while statement are known as the loop head and the loop body?
The syntax of while is: while (expression)statementThe 'while (expression)' part would be then 'head'; the 'statement' would be the 'body'
What is a nested loop in java?
A nested loop is a (inner) loop that appears in the loop body of another (outer) loop. The inner or outer loop can be any type: while, do while, or for. For example, the inner loop can be a while loop while an outer loop can be a for loop.
What are the similarities of while loop and a do while loop?
They both loop
Difference between fixed loop and variable loop?
Fixed loop: this is the loop where the number of iterations are known. Variable loop: Here the number of iterations are not known Example for a variable loop. The pseudocode for variable whille loop begin character cchoice display"enter the choice" accept cchoice while(cchoice='y') begin //execute the statements end end Rkarthikeyan
Does The statements within a while loop execute at least once?
No. If the loop condition is not satisfied then the loop would not be executed even once. while(condition) { ..... /statements ..... } here,when the condition is true then the statements will be executed. Otherwise they would be skipped without being executed. Only for do.. while loops this execution at least once holds good.
Compare Do-While with While Statements?
A Do-While loop looks like this: do { loop body } while (condition); and a While loop looks like this: while (condition) { loop body } The main difference is that the loop body is always run once in the Do-While loop, then the condition is checked to see if the loop should keep running. In a While loop, the condition is checked first, and it will not run the loop body at all if the condition is false.
The while loop is a type of loop?
Is loop
What is a loop type?
A Loop is a programming language construct that instructs the processor to repeat a sequence of operations a number of times until a specific condition is reached. There are different types of loops. They are: * for loop * while loop * do while loop
Definition of do loop while in visual basic?
There are 3 type of loop 1 is for loop 2 is loop while 3 is loop untile
Why you need a for loop when you have already while loop or do while loop?
We need a for loop because the while and do-while loops do not make use of a control variable. Although you can implement a counter inside a while or do-while loop, the use of a control variable is not as self-evident as it is in a for loop. Aside from the use of a control variable, a for loop is largely the same as a while loop. However, it is quite different to a do-while loop, which always executes at least one iteration of the loop before evaluating the conditional expression. In a for and while loop, the conditional expression is always evaluated before entering the loop, which may result in the loop not executing at all.
What is the difference between a for loop and a while loop in java?
ComparisonThe conditions for both the 'while' and 'for' loop are exactly the same, but in each flow structure the conditions are placed in different locations. A 'for' loop places the full condition within the 'for' loop whereas the 'while' loop places the counter variable outside of the loop.The 'for' loop is used when the length of the loop is known whereas the 'while' loop is usually used when the length of the loop is unknown.'for' loop exampleWithin the parentheses the complete condition is contained. The condition has 3 parts delimited by a colon ';'. The first part sets the counter 'int i' to 0, the second part tells the loop to stop when the counter is 5. The third part tells java to increment the counter by 1 value each time the loop iterates.for ( int i = 0; i < 5; i++)'while' loop exampleWith the 'while' loop the counter is initialized outside of the 'while' loop. Inside the parentheses of the loop the condition is set to stop looping when the counter reaches a value of 5. Inside of the 'while' loop block the counter is set to increment by 1 value each time the loop iterates.int i = 0;while ( i < 5 ) {i++}
Can you write switch statement with in while loop?
Yes. The same goes for for-loop and do-while-loop.
